The oracle text on the Born of the Gods card, Phenax, God of Deception states that Phenax is not a creature if your devotion to blue and black is less than 7. However, the card is a Legendary Enchantment Creature, so if your devotion is not enough for Phenax to be a creature, would casting it be a creature spell (could it be countered by Nullify or other cards that specifically counter creature spells)?
